Filter interconnect using a correlated magnet torque design

Abstract

A filtration system interconnection structure having manifold with a rotatable manifold magnet of correlated magnets, a shroud with alignment tracks, an actuating valve for water ingress, and a filter cartridge having a rotatable filter magnet of correlated magnets, where the manifold magnet and the filter magnet are in magnetic communication with one another when the filter cartridge is inserted with the shroud, and are at least partially rotatably compatible, where the manifold magnet rotates with the filter magnet until the manifold magnet experiences a rotational stop beyond a predetermined rotation of the filter magnet, thus allowing the filter magnet to shift polarity with respect to the manifold magnet and present a repulsion force for removal of the filter cartridge from the shroud.

Thus, having described the invention, what is claimed is: 
     
       1. A filter cartridge comprising:
 a housing body having a side surface and top surface with a stem extending therefrom, and a filter boss extending radially outwards from said side surface; 
 said stem including ingress and egress ports for fluid flow, and a filter magnet including a coded, correlated magnet having an array of field emission structures having multiple magnetic field emission sources for magnetic interaction with complementary magnets on a manifold, said filter magnet positioned on a top surface of said stem or within said stem adjacent said top surface; and 
 filter media located within said housing body. 
 
     
     
       2. The filter cartridge of  claim 1  wherein said array includes magnetic field emission sources forming a predetermined design such that upon alignment with a complementary magnet causes a peak spatial attraction force. 
     
     
       3. The filter cartridge of  claim 1  wherein said stem covers said filter magnet that allows for magnetic attraction and repulsion forces from said filter magnet to transmit therethrough, such that said filter magnet is separated from external elements by a physical barrier. 
     
     
       4. The filter cartridge of  claim 1  including wherein said stem includes a spool valve having separately located channels for directing water ingress and egress to and from said filter media. 
     
     
       5. The filter cartridge of  claim 1  wherein said stem is a side-loaded structure having water ingress entering radially inwards, and water egress exiting radially outwards. 
     
     
       6. The filter cartridge of  claim 1  wherein said filter boss is shaped to be received within a receiving channel within a shroud of a manifold.
